Fire-fighters in London have said that in the past 3 years there have been 79 handcuff mishaps.
They asserted that there have been nine instances of men who have had rings stuck on their penises; they also urged people to keep the keys handy.
They said that previously the crew has been summoned to rescue a man whose penis was stuck in a toaster, and another whose penis was trapped in a vacuum cleaner, the Daily Express reported.
Third officer Dave Brown said that he didn't know if it was the '50 Shades' effect, but the incidents involving items like handcuffs had risen.
